Given a morphism of spaces $f: T\to S$, and a diagram indexed by $T$ in $Cat_{(\infty,1)}$, $F: S\to Cat_{(\infty,1)}$, by pre-composition $T\to S\to Cat_{(\infty,1)}$, we get a new diagram $Ff: T\to Cat_{(\infty,1)}$. By taking the colimits, we have a morphism colim$_{\xi\in T} F(f(\xi))\to $co...

Let a point charge $+q$ be moving with constant velocity $\boldsymbol v$. At some moment, its position vector with respect to the origin is $\boldsymbol x$. We need to find the magnetic flux density $\boldsymbol B$ at the origin. If we apply Biot-Savart law, $$\operatorname d\boldsymbol B=\frac{\...

Hebrews 10:22 ESV "Let us draw near with a true heart in full assurance of faith, with our hearts sprinkled clean from an evil conscience and our bodies washed with pure water." [My emphasis]. Is "full assurance" a way of describing "faith", i.e., anything less than "full assurance" is not "faith

First source: https://dornsife.usc.edu/news/stories/what-is-a-miracle/ More than medicine The word is used widely in nonreligious ways.

On season 9 of Last Man Standing, Mike Baxter (Tim Allen) meets Allen's previous sitcom character, Tim Taylor. Having them on-screen talking with each other is no big deal; we've seen TV and movies pull that trick off for decades now using a split-screen, but I don't think I've ever seen two vers...

There are some new security companies selling what they call "enterprise browsers". For instance, Island (https://www.island.io/blog/what-is-an-enterprise-browser) is one of them.

I'm currently writing a post-apocalyptic story set in modern times—the 21st century. 10 years ago, a calamity I've yet to name (let's call it The Darkness for now) appeared in response to the collective despair of humanity and has been ravaging the world ever since. The Darkness is a unique subst...

Has deep learning discovered any heretofore unknown algorithms? Goodfellow et al. give an example of learning XOR, and the Universal Approximation Theorem seems to imply that deep learning might be able to represent any algorithm (or Turing machine?).

I have some cards of feathers with transparency on EEVEE, and I want to set parent to the rig of a bird with rigify but it says "failed to find solutions for one or more bones". I know that this is because the mesh is separate in cards, but I want to know if there is some way I can parent the car...

I'm attempting to reverse engineer a window curtain motor board. I'm very much a electronics beginner. The board has two ICs marked "7E" (labeled Q3 and Q4) that I'm unable to determine was it is.

If you use two torches, one with a red filter/gel attached and one with a green, you can combine the projected light to create yellow, but why then can you not use both filters on a single torch to generate the same result?

I am using ESP32-S3 for sending I2S signals to an external class D amplifier (MAX98357a) that takes in PCM data input and outputs the amplified signal into a speaker. Which then with the help of his speaker coils "filters" out or converts the digital signal and makes sound. Now, i want to send tw...

I am trying to align (perfectly and properly) a TIFF file with either Google's map or the OpenStreetMap (or any other, if there are any decent ones). I have tried so many different version, some simple, some very complex. But none fully align. This is the closest I have gotten: import rasterio fr...

Context for the question: I am studying Legendre transforms in statistical mechanics. I have read that the Legendre transform allows us to transform between conjugate variables in expressions. For example, if I begin with $E(S,V,N)$, a Legendre transform can get me to $E(T,V,N)$. The confusion co...

I'm trying to identify a The Tracey Ullman Show episode where Tracey Ullman applies for a job playing Peter Pan. She reveals that she has a comic book super power: she can really fly.

I am wondering if one can obtain the cycle graph $C_6$ given the degree sequence $D = (2,2,2,2,2,2)$ using the bottom-up construction resulting from the recursive sequences in the Havel-Hakimi algorithm.

I was making a galaxy in Blender version 2.91, but I knew if I get the nodes to Blender version 4.2 it wont work, as I used MixRGBs and the Emission from the Principled BSDF and more. Does anyone know how to convert them if it's possible?

I'm in the UK, and I just ordered a new tyre (tire) to be fitted. The receipt says "as a reminder, wheel torque settings MUST be checked within 50 miles of wheels being fitted".

I read this short fiction at least 40 years ago, probably in a collection. Not a novel, possibly a novelette, but probably a bit too long to qualify as a "short story". In this dystopia, long distance car races are organised. The winner (or maybe also a few of the best competitors) is (are) award...

I know Harrington is quite famous for unpublished works in computability theory and a friend of mine specializing in set theory says Woodin is also quite similar which led me to the following question: What are some of the most important/interesting works that were never published by the authors?

Romans 10:9-11 (KJV) 9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. 10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. 11 For the ...

I know that the inverse of sine is used to find angle measures x when given a sine ratio (opposite/hypotenuse). However, my question is more conceptual. I understand how one can use the inverse sine function, or inverse cosine or inverse tangent, to find a missing angle, but I don't know exactly ...

On Sequoia 15.0.1 System settings says the update to version 15.3 is 15.22 GB in size. I assume that's the download size. That's a lot for an update, so I looked up how much the standalone installer for the same version would use, and it's also 15.2 GB. What I expected to be an incremental update...

I have this well stocked pantry and have noticed a little bowing toward the center of the shelves. I’m worried that they may eventually collapse.

In methylene carbene $(\ce{H2C{\bf{:}}})$, what is the hybridization of the carbon atom, as well as electron distribution in the different orbitals? I think since methylene has 2 hydrogens bonded to a carbon with a 'lone pair,' it should have $\mathrm{sp^2}$ hybridization. Then, does it have an...

The short story "Nameless" by Rema Hmoud is told from the point of view of a pregnant woman surrounded by other women of her family. It's peculiarly unrealistic, with the entire pregnancy seeming to take only a few days, and I suspect it's meant as a satirical allegory about Jordanian society: th...

Apologies if this is off-topic or too subjective, but I'm currently trying to translate and interpret one of my favorite Vocaloid songs, 'Floating Shelter' (Lyrics) by ピノキオピー.

If our brains are just complex neural networks, trained throughout our lives on borrowed information, why is using AI to generate text considered 'cheating' or fake? Aren't we all just sophisticated AI systems, paraphrasing and remixing what we've learned? Isn't our brain just another neural netw...

I have completed some basic sculpting around the edge of a simplistic pond object mesh using the grab brush with dynotope mode activated and its detailing set to 'relative detail' to try and keep the grid dimensions as uniform as possible.

The kings can probably touch, as if you protect the square adjacent to the opponent's king.
